AbstractThe authors analyzed factors that may influence the outcome of adult patients with respiratory failure who were treated with ECMO. Between December 1990 and July 1995, the authors used ECMO to support 33 patients (age range, 17-56 years) with respiratory failure from adult respiratory distress syndrome (ARDS; n = 9), primary graft failure after lung transplantation (n = 16), late graft failure after lung transplantation (n = 5), and miscellaneous reasons (n = 3). Twenty (61%) patients were successfully weaned from ECMO, and 13 (39%) survived to hospital discharge. Venoarterial ECMO was used in 46% of survivors, compared with 60% of nonsurvivors (p = 0.43). The time on mechanical support before ECMO and the duration on ECMO for survivors and nonsurvivors was 2.9 +/- 1.8 days vs 5.0 +/- 1.3 days (p = 0.35), and 6.5 +/- 1.8 days vs 5.7 +/- 1.1 days (p = 0.68), respectively. Compared with the nonsurvivors, survivors had higher PF ratios (PaO2/FIO2; 104 +/- 33 vs 81 +/- 8, p = 0.43) before ECMO was initiated, although the differences were not significant. Among the patients who received ECMO for primary graft failure, 75% were weaned from ECMO, and 56% survived to discharge. ECMO is beneficial for adult patients with respiratory failure, especially those with primary graft failure after lung transplantation.
